Hi,

I think I can see where you're going with this and it's something I've 
wanted to do for years but never got to the top of my priority list.

You probably want to output the time and an identifier for the event ( 
and likely some other supplementary data like direction/magnitude in 
some cases).

Fairly obviously, you just hack into the code where it starts 
calculating the response to the brake pedal event , output your line of 
data, and continue.

Are you also a novice programmer? Unless I'm misunderstanding your 
question it seems a bit obvious. Maybe you could specify better what you 
are wanting to do and why you are stuck.

You could write  this to a file or a pipe, the file could /dev/ttyS0 
(assuming linux/unix system, you don't specify). Writing timing data as 
well would mean you don't need to be hard real time (which may not be 
reactive enough) , you could even process it later depending upon 
exactly what you're doing.

If you can better explain what you are aiming to do , without giving 
away any secrets, it may help to give better advice.

best regards.
